Title
(EN) WAVELENGTH SELECTIVE OPTICAL SWITCH
(FR) COMMUTATEUR OPTIQUE SELECTIF A LONGUEUR D'ONDE
Abstract
(EN)
An optical switch for manipulating a plurality of input optical signals incident thereupon to split one or more optical signal channels from the plurality of input optical signals. The optical switch includes an optical filter (22) having a first reflective region (36) and a second reflective region (38). One of the first and the second reflective regions is adapted with a wavelength selective filter that is capable of separating one or more optical signal channels (30) from the input optical signal (26). A translating mechanism cooperates with the optical filter and is adapted to translate the optical filter in a plane substantially parallel to one of the first reflective region and the second reflective region between a first position and a second position. The translation of the optical filter causes at least one of the one or more optical signal channels to be separated from the optical signal and directed in a second direction. Additionally, another of the one or more optical signal channels to be separated from the optical signal can be directed in a third direction.

L'invention concerne un commutateur optique servant à manipuler une pluralité de signaux optiques d'entrée incidents sur le commutateur, pour diviser une ou plusieurs voies de signal optique à partir de la pluralité de signaux optiques d'entrée. Le commutateur optique inclut un filtre optique (22) présentant une première région réfléchissante (36) et une seconde région réfléchissante (38). La première ou la seconde région réfléchissante est équipée d'un filtre sélectif à longueur d'onde capable de séparer une ou plusieurs voies de signal optique (30) à partir du signal optique d'entrée (26). Un mécanisme de translation coopérant avec le filtre optique est adapté pour translater ce dernier sur un plan sensiblement parallèle à l'une des régions réfléchissantes, entre une première position et une seconde position. La translation du filtre optique permet au moins de séparer une des voies de signal optique du signal optique et de l'orienter vers une deuxième direction. De plus, une autre des voies de signal optique à séparer du signal optique peut être orientée vers une troisième direction.
